Abstract EXIOPOL (A New Environmental Accounting Framework Using Externality Data and Input–Output Tools for Policy Analysis) was a European Union (EU)-funded project creating a detailed, global, multiregional environmentally extended Supply and Use table (MR EE SUT) of 43 countries, 129 sectors, 80 resources, and 40 emissions. We sourced primary SUT and input–output tables from Eurostat and non-EU statistical offices. We harmonized and detailed them using auxiliary national accounts data and co-efficient matrices. Imports were allocated to countries of exports using United Nations Commodity Trade Statistics Database trade shares. Optimization procedures removed imbalances in these detailing and trade linking steps. Environmental extensions were added from various sources. We calculated the EU footprint of final consumption with resulting MR EE SUT. EU policies focus mainly on energy and carbon footprints. We show that the EU land, water, and material footprint abroad is much more relevant, and should be prioritized in the EU's environmental product and trade policies.

Notes 1A main problem was that to create an MR EE SUT, one needs to have both the Supply as Use table in basic prices. Under the ESA95 EU member states provide the Use table in purchaser prices, and not for all countries official valuation matrices could be obtained or made public to transform this in a basic price Use table. The need to make estimates for some countries and confidentiality issues led to the solution to publish only an aggregated EU27 table. 2Indeed, one of the reasons to calculate emissions using energy databases (dubbed the ‘energy first’ approach) is that this enabled us to calculate emissions across countries in a fully comparable way. The degrees of freedom left by official emission inventory protocols led to the situation that countries have slightly different approaches to emission inventories. 3Sometimes authors also discern gray water. Gray water use reflects pollution in discharged water. It is calculated by looking at the volume of the discharge and the concentration of pollutants, and calculating to how much the water has to be diluted to be of legal quality standard. This calculation is highly controversial, since it does not take into account the way some substances degrade quickly, whereas others are persistent or (e.g. metals) do not degrade at all (cf. Guinée et al., Citation2002). We therefore did not calculate the gray water use. 4The trade statistics were obtained from the synchronized UN COMTRADE trade database as published by Feenstra et al. Citation(2005). Service trade data were sourced from the UN Service Trade Database. Both data sets needed further elaboration and creation of correspondence tables to the EXIOPOL classification (Bouwmeester, Citation2011). 5This assumption has been referred to as the proportionality assumption. The implications of this assumption are discussed in Koopman et al. Citation(2010) and Puzzello Citation(2012), among others. 6The bi-proportional adjustment method used is GRAS, a generalized version of RAS that can also deal with negative values, such as subsidies and changes in inventories (Junius and Oosterhaven, Citation2003). 7This estimation is crude because any statistical discrepancies, asymmetries, and methodological differences between the data used that affect the structure of the table are also included in this difference. 8Prices are in the range of 1,500 Euro for a single user.
